(Left) Absorption (dashed line) and PL (open circles) spectra of PEC-PIFTEH in 1.7 g/liter solution in p-xylene (a); femtosecond transient absorption spectra of the same solution for various pump-probe delays (b); and transient absorption spectrum at a pump-probe delay of 1,000 ps (c). (Right) Absorption (dashed line), EL (solid line), and PL (open circles) of an ≈150-nm-thick PEC-PIFTEH film (a); femtosecond transient absorption spectra of the same film for various pump-probe delays (b); and transient absorption spectrum at a pump-probe delay of 100 ps (c).
